UMC files patent infringement lawsuit against Micron

United Microelectronics Corporation (NYSE:UMC; TWSE:2303) (“UMC”), a global semiconductor foundry, today announced that the company has filed a patent infringement lawsuit against Micron Semiconductor (Xi’an) Co., Ltd. and Micron Semiconductor (Shanghai) Co., Ltd. in the Fuzhou Intermediate People’s Court of the People’s Republic of China (PRC). The lawsuit covers three areas that allegedly infringe upon UMC’s patent rights in China, including specific memory applications that relate to DDR4, SSD and memory used in graphics cards.

In the complaint, UMC has requested the court to order the defendant(s) to stop manufacturing, processing, importing, selling and intending to sell the allegedly infringing products, destroy all inventory and related molds and tools and demand that Micron compensate the company for a total amount of RMB 270 million in damages.

UMC has devoted a great deal of resources and manpower to researching and developing semiconductor manufacturing technology. Its achievements can be applied to logic chips or memory chips (DRAM), and the company has applied for patents in various countries while continuing to monitor these patents as market conditions evolve. After conducting an in-depth review, UMC found that Micron’s products sold in mainland China did indeed infringe upon the patent rights of the company, and thus patent infringement litigation has been pursued in order to obtain fair judgment.

As IP and IC designers and verification teams tackle increased complexity and expectations, reliability verification has become a necessary ingredient for success. Automotive, always-on mobile devices, IOT and other platforms require increasingly lower power envelopes and reduced device leakage while maintaining overall device performance. Foundries have also created new process nodes targeted for these applications. Having the ability to establish baseline checks for design and reliability requirements is critical to first pass success. January 08, 2018Sponsored by Mentor Graphics

The power amplifier (PA) – as either a discrete component or part of an integrated front end module (FEM) – is one of the most integral RF integrated circuits (RFICs) in the modern radio. In Part 2 of this white paper series, you will learn different techniques for testing PAs via an interactive white paper with multiple how-to videos.September 06, 2017Sponsored by National Instruments

Since 2006, many of new 3D NAND Flash cells have been proposed and commercialized on the market. Already, we have seen 3D NAND cell structure up to 64L/72L with single or multi-stack NAND string architecture. The memory density on Micron/Intel’s 64L 3D NAND 256 Gb/die reached 4.40 Gb/mm2 (256 Gb/die). In this session, we’ll overview 3D NAND Flash roadmap, products, cell design, structure, materials and process integration. The 3D NAND cell architecture from major NAND manufacturers including Samsung TCAT V-NAND, Toshiba/Western Digital BiCS, SK Hynix P-BiCS and Micron/Intel FG CuA will be reviewed and compared. Current and future technology challenges on 3D NAND will be discussed as well.

MEMS have quite different process and material requirements compared to mainstream microprocessor and memory types of devices. We will explore the latest trends in MEMS devices – including sensor fusion, biosensors, energy harvesting – new manufacturing challenges and potential equipment and materials solutions to those challenges.
